Since the water faucet leaked 2 1/6 liters every 1/3 of an hour, in order to find the leak rate, we need to divide those two numbers. So we proceed to convert the mixed number 2 1/6 into a fraction, to make the division simpler:
2 1/6 = 13/6
Now we divide this fraction by 1/3 (recall that division of two fractions is thesame as the product of the first one time the second one inverted/reciprocal)
This gives us:
13/6 divided by 1/3 = 13/6 * 3/1 = 13/2 = 6.5 liters per hour.
They may want you to answer in fraction form (in which case you use 13/2 liters per hour), or in decimal form (in which case you use 6.5 liters per hour).
